Abstract: 1,113,936. Printing calculator. ING. C. OLIVETTI & CO., S.p.A. 23 Ju.ly, 1965 [1 Aug., 1964], No. 31432/65. Heading G4B. In a ten-key printing calculating machine adapted to simultaneously accumulate an amount in two different sections of a totalizer, said sections 2, 3 co-operate with two groups of actuators 4, 5 controlled by a stop-pin carriage 7 settable order by order through members 23 and keys 22. As shown, for recording transactions, slide 48 is in position I, and the various keys 22 are sequentially depressed and members 23 through projections 24, 25 set up pins 8 in column groups 18, 19 respectively. Movement of member 23 also sets up an escapement stop pin 20 thus causing carriage 7 to be shifted to the left and zero stop plates 28, 30 to release the lowest order actuators 5 and 4. Upon depression of an ADDITION key (not shown), bar 6 releases the actuators 4, 5 which are differentially moved upwards until their shoulders 9 are arrested by set pins 8, thus positioning the type wheels 11 of both groups 16 and 17 co-operating with actuators 4 and 5 respectively. The type wheels of group 16 are allowed to print the set up amount on paper strip; the type wheels of group 17 are prevented from printing by bail 55 engaging projections 57 on the hammers 12. Thereafter, the totalizer sections 2, 3 are engaged with the actuators 4 5, which are restored to their original position by bar 6. When the total key 43 is depressed, levers 38, 33 lock the actuators 5 and thus prevent the type wheels of group 17 from printing the total of the transaction which is printed by group 16 type wheels. The actuators 5 may be similarly locked by depression of the subtract key 45 which may be used to calculate the change to be paid to a customer. The grand total, i.e. the day's business is printed out by moving slide 48 to position II whereby bail 55 is tipped by link 54 and lever 33 is prevented from locking actuators 5 by end 47 of slide 48. Total key lever 43 is depressed and section 3 of the totalizer is cleared and printing out is performed by the type wheels of group 17.

Abstract: 1,225,294. Processing leather. SVIT NARODNI PODNIK. July 10, 1968 [July 14, 1967], No. 32802/68. Heading C6C. A machine for stretching leather comprises a frame 14 which is rectangular as seen in plan, having its longer frame members arranged transverse to the direction of leather feed which is shown by the arrow, a set of discs 16 journalled independantly in swivelling forks on each of the transverse frame members, with each disc of one set arranged opposite a disc of the other set to engage the leather between them, one or, preferably, two rollers which may be either cylindrical or, as shown, double frusto-conical, arranged above the sets of discs and adjustable perpendicularly to the frame 14 by screws 23 so as to bear adjustably against the discs and thereby determine the inclination of each pair of discs and hence the amount of initial stretching of the leather, and a pair of exit rollers 6 which are helically formed to produce final stretching of the leather. The discs are caused to bear against the roller or rollers by springs (20) Fig. 2 (not shown) acting in the appropriate rotational direction on the respective swivel mountings. Whereas in the arrangement shown, using double frusto-conical rollers, differing inclinations of the discs is obtained to give greater stretching towards the edges of the leather, replacement of these rollers by cylindrical rollers allows equal or zero inclinations of the discs to be obtained Figs. 3 and 4 (not shown).

Abstract: 1,227,878. Film-metering devices. FERRANIA S.p.A. June 10, 1968 [June 10, 1967], No.27532/68. Heading G2A. A film-metering device comprises a spiral groove on the film winding knob, along which a ball is guided. As shown, the groove 15 is formed in the surface of the winding knob 10<SP>1</SP>, which is coaxial with the take-up spool 5. A ball 17 is retained between the groove 15 and the inner surface 16 of the camera, which has a transverse groove 24 running across the spiral groove 15. Thus as knob 10<SP>1</SP> is turned, the ball is guided by both grooves, and so moves along the path of the transverse groove 24. Spiral groove 15 is provided at intervals with a series of depressions 18, 19, 20, etc. which form detent seats. When the ball reaches one of these, it tends to be retained therein, thus acting as a metering device. The cylindrical boss 11, which is an integral extension of spool 5, has a reference mark thereon, which reads against an exposure-counting scale on the outside of the camera casing. Alternatively a portion of the casing may be transparent, and the spiral groove observed directly. Such a metering arrangement may conveniently be used for non-perforated film.

Abstract: 1,231,566. Semiconductor devices. MITSUBISHI DENKI K.K. 11 June, 1969 [13 June, 1968], No. 29521/69. Heading H1K. An integrated circuit is produced on a body of semi-conductor material of one conductivity type by providing a highly doped region of the opposite conductivity type on part of one face, growing a layer of material of the one conductivity type on that face, growing a layer of material of the opposite conductivity type on the first grown layer, and causing impurities to diffuse from the highly doped region into the portion of the first grown layer in direct contact with it to convert this portion to the opposite conductivity type during a heat treatment. As shown, Fig. 2c, an N + type region 12 is formed in the surface of a P-type Si substrate 10 by selective diffusion and is covered with a P- type epitaxial layer 20 and an N-type epitaxial layer 14. Selective diffusion is utilized to form a P-type isolation region 16 extending from the surface to the P-type layer 20 and during this diffusion impurities diffuse from the N + type region into the overlying part of the P-type layer 20 to form N-type region 22. A P-type region 18 is then diffused-in to form a diode and electrodes are applied to region 18 and to the exposed part of region 14 encircled by the isolation region 16. The P- and N-type epitaxial layers may be produced by continuous growth, the impurity being changed when desired. The diode region 18 and the isolation region 16 may be simultaneously produced by a single selective diffusion step. Other types of semi-conductor devices may be formed in isolated regions e.g. transistors. The resistivity of the N-type epitaxial layer may be measured using a fourpoint probe before the formation of region 22.

[Also in Division F2] A device for reciprocating diametrically opposed percussion members 20 in guides 22 which are secured to the frame of a percussion tool, comprises eccentric weights 10 mounted on a shaft 12 which is supported for rotation in a body 16 by bearings 14 and a flange 26 radially projecting from the shaft for defining a slit 40 through which lubricant can pass from a chamber 24 to the bearings 14. The lubricant is fed into the chamber 24 through a bore 30 in the shaft and a bore 28 in the flange. The shaft 12 is continuously rotated by a motor and this is transmitted to the eccentric weights which cause a reciprocating motion. Each time the motion of the device is reversed during reciprocation, lubricant is thrown against the periphery of the flange and some passes through the slit 40 to the bearings 14.

Abstract: 1,259,303. Etching. GENERAL ELECTRIC CO. 23 Jan., 1969 [1 Feb., 1968], No. 4019/69. Heading B6J. A body, such as a sheet, of etchable copolymer comprising etchable polymer and non-etchable polymer is bombarded on its surface with charged particles to produce straight tracks of damaged copolymer, an etchant then being applied to remove material along the tracks and produce recesses or apertures in the body. Etchable polymers are polycarbonates, polyethylene terephthalate, crystalline polyethylene, polystyrene and cellulose esters. Unetchable polymers are polytetrafluorethylene and elastomers. The etchant is hydrofluoric acid, sodium or potassium hydroxide, or potassium permanganate. The particles may be argon or oxygen ions or alpha particles, or fission fragments of uranium 235 or californium 252. The particle packs and thus the tracks may be made parallel by interposing a solid apertured sheet. The sheet may be bombarded while stretched, and then etched while still stretched or after being released. The unetchable polymer forms from 1-90% of the copolymer. The recesses or apertures are cylindrical, frusto-conical or of hour-glass shape, and can be widened, or recesses converted into apertures, by further etching. The product can be used to form porous contact lenses or filters, such as molecular sieves. The recesses and apertures can be filled with material other than the surrounding copolymer, for example iron particles to form a ferromagnetic sheet.
